COUNTING OR ADDING MECHANISM FOR CASH-REGISTERS.

SPECIFICATION forming part of Letters Patent No. 631,231, dated August15, 1899.

Application filed September 10, 1898. Serial No. 690,631. (No modelfi Towhom it may concern:

Be it known that I, GEORGE Sorrosrna, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented. certain new and useful Improvements in Counting or AddingMechanism for Gash-Registers; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in counting or adding mechanism foruse in multiple or total-adding cash-registers and other similarmachines.

The object of the invention is to simplify and reduce the mechanism forcounting or adding the numbers representing the cash receipts.

A further object of the invention is to so construct and place thecounting or adding wheels that they may be grouped together and viewedfrom a single point in the machine.

In a detailed description of the invention reference is made to theaccompanying drawings, of which-*- Figure 1 is a side elevation, partlyin section, showing my improved mechanism for counting or adding cashreceipts. Fig. 2 is a front elevation. Figs. 3 and 4; are detached planand sectional views of the retainingsprings for holding the wheelsagainst any backward movement. Fig. 5 is an elevation of one of thelower spur-wheels,adjacent ratchetwheel, and pawl.

I have not shown my invention applied to any particular form ofcash-register, as it is my purpose to apply it to one of my owninvention.

In a detailed description the numerals 1 2 3 4 5 6 designate the addingor counting wheels, which bear figures on their faces, near the rims,denoting the cash or money deposited in the machine, from units up toany denomination. As shown in the draw ings, the said wheels have acapacity for adding a sum as high as nine hundred and ninetyninethousand nine hundred and ninety-nine.

These wheels are constructed in concavo-convex form, so that they mayfit within each other and present their indicating-faces in a commonplane, as shown in Fig. 1. The larger one of said wheelsto wit, wheel1-is the units-wheel, while the smallest one-to wit, wheel 6-is that ofthe highest denomination. Wheel 1 has an integral sleeve or hollow shaft7, which is journaled in a frame 8. The inner end of said hollow shaftterminates with the gear-wheel 9, which is rigidly attached thereto. Ona face of said wheel 9 there is a rigid ratchet-wheel 10, through whichthe sleeve or shaft 7 and wheel 1 are rotated. This rotary movement isimparted by aloose wheel 11 on the said hollow shaft and which has aspring-pressed pawl 12, that engages with the wheel 10 and transmitsvariable movements thereto or movements corresponding to the amount orvalue of the key or keys in the register that operate with theunitswheel 1. The mechanism interposed between the key or keys and thewheel 11 maybe any that has a function of rotating said wheel upon eachoperation of said key or keys. The tens-wheel 2 has ashaft 13 similar toshaft 7 of wheel 1, but smaller. Shaft 13 passes through shaft 7 togear-wheel 1 1 and terminates at said wheel. The latter wheel is fast onthe shaft 13 similar to wheel 9. On the face of wheel 14 there is aratchet-wheel l5, rigidly connected, which receives a springpressed pawl16 similar to 10 and 11. Pawl 16 is carried on a loose gear-wheel 17 onshaft 13. Wheel 17 is driven in a manner similar to wheel 11, only thatthe tens series of keys in the register operate in connection with it.The hundred or dollar wheel 3 has a hollow shaft 18 similar to shafts 13and 7 and which passes through shaft 13 and terminates at wheel 19. Thislatter wheel and wheels 20 and 21, together with pawl 22, operate thesame in connection with shaft 18. Shaft 23 of the tens-of-hundreds wheel1 telescopes with shaft 18 and terminates with rigid wheel 24;, havingadjacent ratchet-wheel 25, loose geanwheel 26, and pawl 27, all of whichoperate in the manner hereinbefore stated. Shaft 27 of wheel 5telescopes with or passes through shaft 23 and terminates with rigidgear-wheel 28, having adjacent ratchetwheel 29, loose gear-wheel 30, andpawl 31.,

all operating to move wheel 5 in the manner described. The centerorsmallwheel 6, which is the wheel of the largest denomination, is on a solidshaft 32, which extends through shaft27 and is journaled in the frame 8.This shaft at the rear end forms the bearing for the entire series ofshafts, while the sleeve or hollow shaft '7 forms a bearing in the outerside of the frame. Shaft 32 has a rigid gearwheel 33 upon it, which istransferred to from wheel 28 by a transfer-pawl 31- aud a gearwheel 35.The latter wheel and pawl are fixed on the sleeve 36, and wheel 35meshes with wheel 28. XVheel 2% transfers to wheel 28 throughagear-wheel 37 and pawl 38, which are both connected with a sleeve Wheel19 transfers to wheel 2% through a gear-wheel t0 and pawl l1, which isconnected to sleeve 42. lVheel 14 transfers to wheel 19 through agear-wheel 43 and pawl it, which are connected to sleeve t5, and,finally, the unitswheel 9 transfers to wheel 14 through a gearwheel 46and pawl 47, connected to sleeve i8. All of the sleeves mentioned in theforegoing in connection with the transferring are loosely mounted 011 ashaft %9, which is supported in the frame.

50 designates a transverse bar which is fastened to the frame in therear of the lower wheels and from which there are a series ofspring-detents 51, that engage with wheels 9, 14:, 2%, 28, and 3% andprevent backward movement of said wheels.

Having fully described my invention, I claim- In a counting or addingmachine, the combination of a series of concavo-convex wheels havingfigures on their rims denoting values from a lower to a higherdenomination, said wheels being of varying sizes and fitting one withinthe other with suitable space between them to avoid friction whenmoving, a series of hollow shafts to the ends of which said wheels arefixed, the said shafts varying in lengths and fitting one within theother, the rear end of the innermost shaft being projected beyond theends of the remaining shafts, and journaled in the frame to constitutethe hearing at the rear end for all said shafts, the outer tubular shaftbeing journaled in the front of said frame and constituting the bearingfor the front ends of all of said shafts, a loose spur-wheel on each ofthe outer shafts, a spur-wheel and a ratchet-wheel fixed to each of saidshafts and movable simultaneously from the loose spur-wheels, a parallelshaft mounted above, a series of spurwheels loosely mounted on saidparallel shaft, a sleeve connected to each of said spur-wheels, and thelatter spur-wheels engaging with the spur-wheels on the tubular shafts,a series of transfer-pawls carried on said sleeves and. engaging withthe tight spur-wheels on the tubular shafts on each complete rotation ofsaid sleeves, substantially as and for the purposes specified.

I11 testimony that I claim the foregoing as my own I hereto aiiix mysignature in presence of two witnesses.

GEORGE SOIIUSTER.
